This is probably due to the fact that your raster values are beyond 255. Mapserver truncates this to 255 which interpreted as white on a greyscale. To correctly scale the values you can use band processing options:
PROCESSING "SCALE=<low>:<high>" You can also use "AUTO" but that might result in strangely "tiled" images.
